Ianto woke up on his stomach, his face pressed into the pillow. He stretched his lean body out experimentally, wincing at the soreness that seemed to radiate out from the center of his being. He didn't mind Jack going at him more than once in a night, but there were times when the immortal could be more than a little rough. Well, not rough, exactly, but he still didn't quite seem to fathom that Ianto wasn't used to being on the receiving end of marathon sex sessions.

Still, last night had been fantastic, in a way. By the third time, Ianto had been gasping and panting, begging Jack to let him get some rest, and the other man had reluctantly done so. But he'd still kept an arm wrapped protectively around Ianto as the younger man had fallen asleep, and somehow, that embrace had felt safer and more comfortable than any other he'd ever felt. Jack had a way of making him feel treasured.

The arm wasn't around his waist any more; in fact, Jack wasn't in their bed. Ianto lifted his head and peered around the room with a frown. It wasn't like Jack to get out of bed early in the morning -- unless something had happened. He was instantly on the alert, starting to sit up and get out of bed. If something was going on, he wanted to be part of it.

As if on cue, Jack appeared in the doorway, shaking his head at Ianto. "Nothing to get out of bed for. Just answering the call of nature." The immortal made his way across the room, sitting down on the bed next to his boyfriend and leaning over to press a kiss to Ianto's parted lips. Ianto closed his eyes, luxuriating in Jack's touch.

Jack's strong hands were turning him over, back onto his stomach, moving down his back, over the curve of his ass, spreading his legs to stroke between his thighs. Ianto couldn't help wincing; he was still sore from last night, his body protesting the very idea of Jack taking him again. It was pleasant while it was happening, but he had a feeling that he'd bitterly regret it if he let Jack do what he was obviously going for.

"Jack ...." Ianto didn't quite know how to tell the other man "no." It wasn't a word he was good at saying, he reflected, especially in this kind of context. And when it came to sex, Jack definitely wasn't a man who wanted to hear that word. He was used to hearing "yes" from anyone and everyone, and having the man he'd chosen to take to his bed in a somewhat permanent manner tell him no probably wasn't going to do a lot for their relationship.

But Jack seemed to sense his mood, those fingers between his legs stopping their movement to stroke down his inner thighs. "Still sore, baby?" he whispered, leaning close to Ianto's ear, his tongue flicking out to tease the younger man's earlobe. "There's ways around that. Nothing to get upset about. It's not like I have to be inside you to make us both feel good."

"You did go at me quite a lot last night," Ianto murmured, not wanting to sound as if he was rebuking the captain for doing so. He'd thoroughly enjoyed everything Jack had done to him; he just hadn't expected to be this sore the next morning. But this was something Jack seemed to be used to, so he wasn't going to question the other man's words.

He could feel Jack moving to the side of the bed, then rolling back over to rest right behind him. Jack turned him onto his side, leaning down to kiss him again. Ianto closed his eyes and leaned into the kiss; there was something about the touch of Jack's lips on his that made him want to throw caution to the wind and promise the other man anything.

Those insistent fingers were probing between his legs again, this time feeling slippery with what could only be lube. Ianto was puzzled for a moment -- it felt as if Jack was coating his thighs with lube, instead of moving his fingers up higher to press against his entrance. This was something new and different, but he should be used to that by now, he thought with an inner smile. Every experience with Jack was different.

He shifted a little, stating to turn back onto his stomach and spread his legs, to give Jack better access. The immortal shook his head, speaking softly into Ianto's ear. "No, you don't have to move. Just lay on your side and relax. You'll enjoy this, Ianto. It's a little unusual, but I'm not going to insist on anything else when you're sore. The last thing I want to do is hurt you."

Ianto did as he was told, letting himself relax as much as he could. He couldn't release all the tension from his body, as he always wondered just what Jack was going to do to him and that made him unable to relax completely. But he trusted Jack; he knew that his lover wasn't going to harm him in any way. And that touch was so sensual ....

Jack's arm wrapped around his waist again, pulling him back against the other man. Ianto gasped when he felt Jack's erection pressing against the curves of his ass, eyes widening. He was always a little startled to feel something so big and knowing where Jack intended for it to go -- that little voice in the back of his mind would scream each time that it was too big, that it was going to hurt, and at least a dozen other things that he didn't want to hear.

But it never hurt; at least not for more than the quicksilver flash of pain when Jack first entered him. Ianto had been tense and nervous the first few times they'd made love, but he'd quickly learned how to relax and enjoy being taken. There was something seductive about giving up control, letting Jack overwhelm him and mold him to the other man's specifications, letting Jack do whatever he wanted with him.

"Keep your legs together, Ianto," Jack whispered, moving a hand over his hip and splaying his fingers out. "I think you'll enjoy this. Just relax, lay back and let me do the driving, okay? Just remember to keep your legs closed. Don't spread them, no matter how much you might want to. You'll figure out why after a few minutes."

He could feel Jack's cock slipping between his thighs, moving back and forth against the soft skin, nudging against his balls with every thrust. It took a conscious effort for him to keep his legs closed; he wanted to roll over and spread his thighs, take Jack into himself as he'd done so many times since they'd started their relationship. But Jack had told him not to -- and if there was one thing Ianto Jones was good at, it was obeying his captain.

Jack was right, Ianto thought to himself, his mind whirling. This did feel good, almost as good as having Jack inside him. Jack's hands were moving over the front of his body, one hand wrapped around his cock, stroking in rhythm with his thrusts. Ianto could already feel his orgasm coiling in the pit of his stomach, ready to break free and wash over him at any moment.

The friction between his thighs was building, making him push his ass back against Jack's body, his hands starting to curl into fists. Jack must have seen his reaction; the immortal removed his hand from Ianto's cock and took the young man's hands in his, twining their fingers together, his thrusts becoming more erratic. The rhythm he'd built up was starting to break as both of them approached orgasm, more quickly than either man had anticipated.

Ianto was the first to let go, crying out Jack's name as he came, his slender body spasming in the other man's arms. He could feel Jack's release, hear the quick, sharp intake of breath right at his ear, the voice that whispered his name over and over. Ianto let himself go limp, breathing heavily, his senses reeling. This was yet another thing to add to his growing stockpile of reasons to call Jack's lovemaking "avant-garde."

"I thought you'd like that," Jack said softly, his lips caressing Ianto's cheek. "It's not something I'd ordinarily do, but I didn't think you were up to anything else I had in mind."

"Indeed not," Ianto agreed, finally catching his breath enough to speak. "I wouldn't mind doing that more often, actually," he continued, craning his neck so that he could turn his head to look at Jack, propped up on an elbow behind him. "It was .... interestingly different."

Jack burst into laughter at Ianto's words, shaking his head. "That's one thing I love about you, Ianto," he said, pressing a kiss to the young man's bare shoulder. "The way you put things. Only you could come up with a phrase like 'interestingly different' and make it sound like a major compliment."

"It is a compliment!" Ianto protested, laughing along with Jack. "My brain is a bit muddled at the moment. It's the best I could come up with on short notice. I'll try to do better later, if you're still fishing for compliments on your bedroom manner."

"Oh, I think that one will do just fine," Jack murmured, lowering his head and capturing his young lover's lips with his own. His hands began to roam down the front of Ianto's body, teasing, caressing, making Ianto groan with need.

"If you keep that up, I may forget that I'm still sore," he whispered, managing to get a few words in between his soft gasps each time Jack's nimble fingers found a new way to arouse him.

"I wouldn't have a problem with that," Jack answered, turning the young man over onto his back and letting his mouth follow the path of his hands. Within moments, Ianto was arching up against him, hands buried in Jack's hair, moaning his name. He was sure that he'd regret this later -- but for now, there was nothing else he wanted more.
